Use Mesh Modeling with Subdivision Surfaces



Hi Jason,
The mesh in your file is very high poly, which often makes it more difficult to edit. Next time, try using poly mesh modeling with a subdivision surface modifier.

Try capturing the shape with as few polygons as possible, and let the modifier help give the appearance of a smoother surface.It's usually easier to edit when there's less geometry to work with, and the modifier will still give the benefit of appearing more detailed than the base mesh actually is.

You can add extra edge loop cuts to sharpen areas, and you can increase and decrease the view count in the subdivision surface modifier. You can even crease your mesh in the N Properties panel under the transform section. Have a look at the image and the blend file provided.

If you often model these kinds of objects, consider taking a look at Claas Kuhnen's youtube videos. He often does product design and concept modeling tutorials that you may find useful.
